MACHINE FOR SHAPING SHEET MATERIALS.

' Application filed September 30, 1921. Serial No. 504,410.

To aZZ whom it may concern:

Be it known that I, JULIUS BRENZINGER, a citizen ofthe United States,and a resident of Fairfield, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inMachines for Shaping Sheet Materials, of which the following is aspecification.

This invention relates generally to a machine for fianging, beading, orotherwise shaping, by pressure, bodies of sheet material and has moreparticularly reference to a machine for producing, by pressure, aknurled portion and a thread in a previously formed cap of sheetmaterial, the character of the cap being that usually employed inconnection with bottles for containing chili sauce or catsup. 'While theshaping of a cap of this character is one of the objects of thisinvention, it'will be understood that, so far as certain features of theinvention are concerned, the character of the body and the shape to beimparted to it is immaterial. I

The main object and feature of the invention is the roduction of amachine for quickly and e ciently shaping previously formed bodies ofsheet material while coming in a constant stream from a hopper or from abody-forming or other machine, the bodies being fed automatically to themachine, properly positioned therein with respect to the shaping tools,shaped while traveling through the nachineand finally automaticallystripped or delivered. In this manner a greatly increased production isobtained.

Other features of the invention will appear as the specificationproceeds.

In theaccompanying drawings, the invention is embodied in a concrete andpreferred form in which:

Figure l is a front elevation of a machine embodying the invention:'

Fig. 2 is an end elevation, part-1y in section on the plane of line 2-2of Fig. 1:

Fig. 3 is a horizontal sectional view on the plane of line 33 of Fig. 1:

Fig. 4 is an irregular vertical sectional view substantially through thecenter of the machine on the plane of line 44 of Fig. 1:

Fig. 5 is a vertical sectional view on the plane of line 55 of Fig. 1showing more particularly the shaping head:

Fig. 6 is a vertical sectional view on the is here a plane of line 66 ofFig. 1 showing more particularly the feeding head:

Fig. 7 is an irregular sectional view on the plane of line 77 of Fig.4;:

Fig. 8 is a detail sectional view on the plane of line 88 of Fig. 4showing' the body being shaped by the tools: and

Fig. 9 is a view similar to Fig. 8 showing the body after it has beenshaped and stripped from the shaping tools.

The product of the machine is shown in Figs. 8 and 9 where, at 1, a capis indicated having, at one end, a closed head 2. During its passagethrough the machine, one portion of the cap is knurled, as at 3, andanother portion is provided with a thread, as at 4.

The machine as here shown comprises two heads 5 and 6 arranged side byside and rotating, either step by step or continuously, in unison andpreferably continuously, between which the body to be shaped is fed, asby means of a chute 7 (Fig. 4), and from which it is delivered, as bymeans of' chute 8. The shaping tools comprise here a stationary member.9 and one or more rotatable members 10 (Fig.8). The stationary member 9acts on the outer periphery and rotatable member 10,-. whichbody-receiving member, on the inner periphery of body 1: and it willtherefore be understood that the inside tool 10 musteither be given amovement projecting it within the body or else the body itself must begiven a movement projecting it over the inside-tool. In cases where thebody being acted upon is open at both ends and the insidetool isprojected within the body, both of the rotating heads may carry tools soas to act upon both ends of the body. In the present instanoe,one end ofthe body is closed and it is preferred to move the body transverselyover the inside tool.

This transverse movement may conveniently be, and here is, effected bymechanism carried by the rotating head 5, and this head may therefore becalled a feeding head. The other head 6, carrying the tools, we may terma shaping head. Any suitable means may be used to rotate the two heads,such as gears ll'and 12, carried by the heads, and pinions 13 and 14carried by a power shaft 15, the heads being loosely mounted on astationary shaft 16.

' or to gear The feeding head 5 carries a body supporting member 17bolted thereto (Fig. 7) 11 carried thereby; and this member 17 is inalignment with chutes 7 and 8 and consists of a central portion 18(Figs. 4 nilmber) of pockets 19, and having cheek plates 20. Duringrotation of the heads, bodies 1 coming from chute 7 fall into pockets19, and in alignment, transversely, w th these pockets are shaping tools10, carr ed by the shaping head, and reciprocating member 21, carried bythe feeding head. These reciprocating members serve to move the bodiesfrom pockets 19 into position on tools 10 and also to strip the bodiesfrom said tools in a manner to be explained. The construction of thesereciprocating members is as follows: the feeding head is provided withfour guides 22 (Fig. 6) and in each of these guides is a slide 23actuated by means-of a stationary cam 24, in which latter travel camrollers 25 connected with the slides. It will be understood from theforegoing that the revolution of the feeding head causes transversereciprocation of slides 23. Each of said slides carries a spring seatedplunger 26, the outward movement of which is limited by stop member 27acting against abutment 28. urrounding the outer end of plunger 26 is asleeve 29 and extending out through the end of said sleeve is a stem 30having a presser head 31. At its inner end, said stem carries aball-shaped head 32 bearing against antifriction balls 33 seated inplunger 26, this construction being provided to admit of easy rotationof the presser head 31 when pressing the body over rotating shaping tool10. Sleeve 29 is further provided with a yoke having two rods 34 thatextend through the central portion 18 and cheeks 20 of the bodysupporting member 17 and carry the stripper member 35 (Figs. 3, 4, 8 and9) surrounding the shaping tool 10.

The shaping head carries as supports for the shaping tools 10, a seriesof spindles or shafts 36 (Figs. 3, 4, 5 and 8), each of which is mountedin two bearings 37 and 38, the latter being pivotally supported at 39and the former slidingly supported in boxes 40. By means of set screw 41and lock nut 42, the bearing 37 may be adjusted, this movement beingpermitted by pivotal bearing 38. By these means, each shaping tool 10may be adjusted with res ect to the shaping tool 9; and, to admit oslight yielding in the pressure of shaping tool 10, there is interposeda strip 43 of leather, or other material, between box cap 44 and bearing37. Any suitable means (Figs. 1, 2 and 3) may be used to rotate spindles36 and the shaping tools 10 carried thereby. In the present instance,each spindle 36 is provided with a' pinion 45 engaging with a centralpinion 46 and 7) having a number (here four innaeaeeo moving with gear47 loosely mounted on stationary shaft 16. Gear 47 derives its motionfrom gear 48 mounted on countershaft 49, said countershaft carrying agear 50 meshing with gear 51 on power shaft 15. At its outer end eachspindle 36 carries a shaping tool 10, here composed of a threaded member52, (Figs. 3, 4, 7 and 8) keyed to spindle 36 and a knurled member 53loosely mounted on spindle 36 and held in place by end member 54 tappedinto said spindle.

Shaping tool 9 (Figs. 4 and 8) consists of two curved or segmentalmembers 55 and 56, the former knurled and the latter threaded and bothmounted stationary on fixed shaft 16 and located in the plane of tool10, that is at one side of the plane of supporting member 17 and chutes7 and 8.

A body arriving from chute 7 drops into a pocket 19 ofbody-supportingmember 17 and, during rotation of the parts, slide 23pushes the body on shaping tool lOand, as the latter travels oversegments 55 and 56, the body is properly shaped between the members 9and 10. Slide 23 then returns causing stripper 35 to remove the shapedbody from tool 10 and thereby depositing it in chute 8 which latterpermits it to roll out of the machine.-

Threaded member 52 is fast on, and moves with, spindle 36 at a definitespeed so that its threads may be synchronized with the threaded member56, but knurled member 53 is loose so that it may find its own centerwith respectto knurled member 55.
